In this work, we propose how to load and manipulate chiral states in a Josephson junction ring in the so-called transmon regime. We characterize these states by their symmetry properties under time-reversal and parity transformations. We describe an explicit protocol to load and detect the states within a realistic set of circuit parameters and show simulations that reveal the chiral nature. Finally, we explore the utility of these states in quantum technological nonreciprocal devices.

约瑟夫森结环中的手性态和非互易相

在这项工作中，我们提出了如何在所谓的 transmon 机制中加载和操纵约瑟夫森结环中的手性状态。我们通过它们在时间反转和奇偶变换下的对称特性来表征这些状态。我们描述了一个明确的协议来加载和检测一组真实的电路参数中的状态，并展示揭示手征性质的模拟。最后，我们探索了这些状态在量子技术非互易设备中的效用。
